Swedish customers receiving our shipments via Postnord are mislead to think they have to pay customs fee and VAT....
We currently ship minimum once per week.
Non-Norwegian customers are invited to order from our store on Lectronz.com, a third party sales platform that handles national VAT to EU countries, using the EU IOSS system (for order values up to 150 EUR ex VAT).

Will there be an update of Pow-U with ESP32?
During the design of Pow-U, one of the major challenges was to power it from the M-bus line on the HAN-port. In this way, Pow-U does not need a separate power supply.
We would love to use ESP32 also on Pow-U, but for the time being all versions of ESP32 consume too much power to make this possible. During S1/2022 we upgraded the Pow-K to use and ESP32-S2 module. However, also the S2 consumes too much power to be used on Pow-U.
We'll keep an eye on new products from Espressif, and as soon as a suitable and compatible module hits the market we'll start working on it!
But for the time being, the answer is sadly: No.
Update 5th September 2022
We have great news!
We finally found the solution, and have now redesigned the Pow-U around an ESP32-S2-MINI module. We have ordered a first production batch, and we expect to start shipping the new Pow-U around 1st October -22.

Use Pow-U for Kamstrup
By: Stian On 10-Oct-2022With the new ESP-32-S2-Mini, will Pow-U also be possible to use with Kamstrup? Currently only Pow-K module is said to work with Kamstrup HAN-NVE modules (https://amsleser.no/hjem/7-pow-u-universal.html).
